Abstract
There is a large body of literature demonstrating a social gradient in health and increasing evidence of an association between social deprivation and diabetes complications. Diabetic kidney disease (DKD) increases mortality in people with diabetes. Socioeconomic deprivation is increasingly recognized as a modifier of risk factors for kidney disease but also an independent risk factor itself for kidney disease. This may not be truly appreciated by clinicians and warrants further attention and exploration. In this review we explore the literature to date from Europe on the relationship between social deprivation and DKD. The majority of the studies showed at least an association with microalbuminuria, an early marker of DKD, while many showed an association with overt nephropathy. This was seen across many countries in Europe using a variety of different measures of deprivation. We reviewed and considered the mechanisms by which deprivation may lead to DKD. Health related behaviors such as smoking and suboptimal control of risk factors such as hypertension, hyperglycemia and elevated body mass index (BMI) accounts for some but not all of the association. Poorer access to healthcare, health literacy, and stress are also discussed as potential mediators of the association. Addressing deprivation is difficult but starting points include targeted interventions for people living in deprived circumstances, equitable roll out of diabetes technology, and flexible outpatient clinic arrangements including virtual and community-based care.

Abstract
As regards colorectal cancer (CRC) in France, social inequalities in health (SIH) exist. Underprivileged patients are characterized by reduced incidence of CRC and, conversely, by excess mortality. The explanatory mechanisms of the SIHs influencing survival are complex, multidimensional and variable according to healthcare system. Among the most deprived compared to the least deprived patients, SIHs are reflected by lower participation in screening campaigns, and CRC diagnosis is more frequently given at a later stage in an emergency context. During treatment, disadvantaged patients are more at risk of having to undergo open surgery and of enduring severe postoperative complications and belated chemotherapy (when recommended). Study of SIHs poses unusual challenges, as it is necessary not only to pinpoint social deprivation, but also to locate the different treatment facilities existing in a given territorial expanse. In the absence of individualized socioeconomic information, research in France on the social determinants of health is based on duly constituted cancer registries, in which an ecological index of social deprivation, the European Deprivation Index (EDI), provides an aggregate measure of the socioeconomic environment of a given individual in a given geographical setting at a given point in time. All in all, studies on SIHs are justified as means of identification and comprehension of the mechanisms underlying social deprivation, the objective being to more precisely orient programs and practices aimed at combating SIH.

Abstract
Colorectal cancer remains a significant cause of morbidity and mortality, even despite curative treatment. A significant proportion of patients present emergently and have poorer outcomes compared to elective presentations, independent of TNM stage. In this systematic review and meta-analysis, differences between elective/emergency presentations of colorectal cancer were examined to determine which factors were associated with emergency presentation. A literature search was carried out from 1990 to 2018 comparing elective and emergency presentations of colon and/or rectal cancer. All reported clinicopathological variables were extracted from identified studies. Variables were analysed through either systematic review or, if appropriate, meta-analysis. This study identified multiple differences between elective and emergency presentations of colorectal cancer. On meta-analysis, emergency presentations were associated with more advanced tumour stage, both overall (OR 2.05) and T/N/M/ subclassification (OR 2.56/1.59/1.75), more: lymphovascular invasion (OR 1.76), vascular invasion (OR 1.92), perineural invasion (OR 1.89), and ASA (OR 1.83). Emergencies were more likely to be of ethnic minority (OR 1.58). There are multiple tumour/host factors that differ between elective and emergency presentations of colorectal cancer. Further work is required to determine which of these factors are independently associated with emergency presentation and subsequently which factors have the most significant effect on outcomes.

Abstract
BACKGROUND Access to quality health care and treatment outcomes can be affected by patients' socioeconomic status (SES). PURPOSE To evaluate the effect of patient SES on patient-reported outcome measures (PROMs) after arthroscopic hip surgery. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Demographic, radiographic, and intraoperative data were prospectively collected and retrospectively reviewed on all patients who underwent hip arthroscopy for femoroacetabular impingement syndrome (FAIS) and labral tear between February 2008 and September 2017 at one institution. Patients were divided into 4 cohorts based on the Social Deprivation Index (SDI) of their zip code. SDI is a composite measure that quantifies the level of disadvantage in certain geographical areas. Patients had a minimum 2-year follow-up for the modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), International Hip Outcome Tool-12, and visual analog scale (VAS) for both pain and satisfaction. Rates of achieving the minimal clinically important difference (MCID) and patient acceptable symptom state (PASS) were calculated for the mHHS, NAHS, and VAS pain score. Rates of secondary surgery were also recorded. RESULTS A total of 680 hips (616 patients) were included. The mean follow-up time for the entire cohort was 30.25 months. Division of the cohort into quartiles based on the SDI national averages yielded 254 hips (37.4%) in group 1, 184 (27.1%) in group 2, 148 (21.8%) in group 3, and 94 (13.8%) in group 4. Group 1 contained the most affluent patients. There were significantly more men in group 4 than in group 2, and the mean body mass index was greater in group 4 than in groups 1 and 2. There were no differences in preoperative radiographic measurements, intraoperative findings, or rates of concomitant procedures performed. All preoperative and postoperative PROMs were similar between the groups, as well as in the rates of achieving the MCID or PASS. No differences in the rate of secondary surgeries were reported. CONCLUSION Regardless of SES, patients were able to achieve significant improvements in several PROMs after hip arthroscopy for FAIS and labral tear at the minimum 2-year follow-up. Additionally, patients from all SES groups achieved clinically meaningful improvement at similar rates.

Measuring health-related social deprivation in small areas: development of an index and examination of its association with cancer mortality. Int J Equity Health 2021; 20:216.

Abstract
BACKGROUND The small-area deprivation indices are varied across countries due to different social context and data availability. Due to lack of chronic disease-related social deprivation index (SDI) in Hong Kong, China, this study aimed to develop a new SDI and examine its association with cancer mortality. METHODS A total of 14 socio-economic variables of 154 large Tertiary Planning Unit groups (LTPUGs) in Hong Kong were obtained from 2016 population by-census. LTPUG-specific all-cause and chronic condition-related mortality and chronic condition inpatient episodes were calculated as health outcomes. Association of socio-economic variables with health outcomes was estimated for variable selection. Candidates for SDI were constructed with selected socio-economic variables and tested for criterion validity using health outcomes. Ecological association between the selected SDI and cancer mortality were examined using zero-inflated negative binomial regression. RESULTS A chronic disease-related SDI constructed by six area-level socio-economic variables was selected based on its criterion validity with health outcomes in Hong Kong. It was found that social deprivation was associated with higher cancer mortality during 2011-2016 (most deprived areas: incidence relative risk [IRR] = 1.40, 95% confidence interval [CI]: 1.27-1.55; second most deprived areas: IRR = 1.34, 95%CI: 1.21-1.48; least deprived areas as reference), and the cancer mortality gap became larger in more recent years. Excess cancer death related to social deprivation was found to have increased through 2011-2016. CONCLUSIONS Our newly developed SDI is a valid and routinely available measurement of social deprivation in small areas and is useful in resource allocation and policy-making for public health purpose in communities. There is a potential large improvement in cancer mortality by offering relevant policies and interventions to reduce health-related deprivation. Further studies can be done to design strategies to reduce the expanding health inequalities between more and less deprived areas.

Abstract
Background: Tubo-ovarian cancer (OC) continues to be the most lethal of all gynaecological cancers. Over half of women are diagnosed with late stage (III/IV) disease, which has a five-year survival rate of 11%. Socioeconomic status (SES) has been shown to have an impact on outcomes of several cancer types, including OC. This study aims to investigate any potential association between SES and stage at diagnosis of OC. Methods: Women from the non-screening arm of the United Kingdom Collaborative Trial of Ovarian Cancer Screening (UKCTOCS) with a confirmed diagnosis of OC prior to 01 January 2015 and an English index of multiple deprivation (IMD) score were eligible for the study. The association between IMD and OC stage (FIGO) was analysed using an ordinal logistic regression model adjusted for age at diagnosis and BMI. Results: Four-hundred and fifty seven women were eligible for inclusion in the primary analysis. The odds of being diagnosed with the higher dichotomization of stage (I vs. II/III/IV; I/II vs. III/IV; I/II/III vs. IV) was 1.29 (p = 0.017; 95% CI: 1.048–1.592) per unit SD (standard deviation) increase in IMD. This translates to a 29% increase in odds of being diagnosed at the higher stage per each unit SD increase in IMD. Conclusion: Increased deprivation is consistently associated with a higher probability of being diagnosed with later stage OC.

Abstract
PURPOSE The aim of this study was to assess the effects of socioeconomic deprivation on short-term outcomes and long-term overall survival following major resection of colorectal cancer (CRC) at a tertiary hospital in England. METHOD This was an observational cohort study of patients undergoing resection for colorectal cancer from January 2010 to December 2017. Deprivation was classified into quintiles using the English Indices of Multiple Deprivation 2010. Primary outcome was overall complications (Clavien-Dindo grades 1 to 5). Secondary outcomes were the major complications (Clavien-Dindo 3 to 5), length of hospital stay and overall survival. Outcomes were compared between most affluent group and most deprived group. Multivariate regression models were used to establish the relationship taking into account confounding variables. RESULTS One thousand eight hundred thirty-five patients were included. Overall and major complication rates were 44.9% and 11.5% respectively in the most affluent, and 54.6% and 15.6% in the most deprived group. Most deprived group was associated with higher overall complications (odds ratio 1.48, 95% CI 1.13-1.95, p = 0.005), higher major complications (odds ratio 1.49, 1.01-2.23, p = 0.048) and longer hospital stay (adjusted ratio 1.15, 1.06-1.25, p < 0.001) when compared with most affluent group. Median follow period was 41 months (interquartile range 20-64.5). Most deprived group had poor overall survival compared with most affluent, but it was not significant at the 5% level (hazard ratio 1.27, 0.99-1.62, p = 0.055). CONCLUSION Deprivation was associated with higher postoperative complications and longer hospital stay following major resection for CRC. Its relationship with survival was not statistically significant.

Abstract
BACKGROUND Numerous factors affect the prognosis of colorectal cancer (CRC), many of which have long been identified, such as patient demographics and the multidisciplinary team. In more recent years, molecular and immunological biomarkers have been shown to have a significant influence on patient outcomes. Whilst some of these biomarkers still require ongoing validation, if proven to be worthwhile they may change our understanding and future management of CRC. The aim of this review was to identify the key prognosticators of CRC, including new molecular and immunological biomarkers, and outline how these might fit into the whole wider context for patients. METHODS Relevant references were identified through keyword searches of PubMed and Embase Ovid SP databases. RESULTS In recent years there have been numerous studies outlining molecular markers of prognosis in CRC. In particular, the Immunoscore® has been shown to hold strong prognostic value. Other molecular biomarkers are useful in guiding treatment decisions, such as mutation testing of genes in the epidermal growth factor receptor pathway. However, epidemiological studies continue to show that patient demographics are fundamental in predicting outcomes. CONCLUSION Current strategies for managing CRC are strongly dependent on clinicopathological staging, although molecular testing is increasingly being implemented into routine clinical practice. As immunological biomarkers are further validated, their testing may also become routine. To obtain clinically useful information from new biomarkers, it is important to implement them into a model that includes all underlying fundamental factors, as this will enable the best possible outcomes and deliver true precision medicine.

Abstract
Abstract
Background
Socioeconomic deprivation is a potentially important factor influencing surgical outcomes. This systematic review aimed to summarize the evidence for any association between socioeconomic group and mortality after colorectal surgery, and to report the definitions of deprivation used and the approaches taken to adjust for co-morbidity in this patient population.
Methods
MEDLINE, Embase, the Cochrane Library and Web of Science were searched for studies up to November 2016 on adult patients undergoing major colorectal surgery, which reported on mortality according to socioeconomic group. Risk of bias and study quality were assessed by extracting data relating to study size, and variations in inclusion and exclusion criteria. Quality was assessed using a modification of a previously described assessment tool.
Results
The literature search identified 59 studies published between 1993 and 2016, reporting on 2 698 403 patients from eight countries. Overall findings showed evidence for higher mortality in more deprived socioeconomic groups, both in the perioperative period and in the longer term. Studies differed in how they defined socioeconomic groups, but the most common approach was to use one of a selection of multifactorial indices based on small geographical areas. There was no consistent approach to adjusting for co-morbidity but, where this was considered, the Charlson Co-morbidity Index was most frequently used.
Conclusion
This systematic review suggests that socioeconomic deprivation influences mortality after colorectal surgery.
